(FR) SYSTÈMES ET PROCÉDÉS D'ÉVALUATION ET DE RÉDUCTION DE LA DYSPHOTOPSIE NÉGATIVE
Abstract
(EN)
Systems and methods for evaluating ND are described herein. An example method can include constructing a non-sequential (NSC) ray-tracing model of an eye with an ophthalmic lens, and modelling a light source and a detector. The detector can be configured to mimic a retina of the eye. The method can also include computing irradiance data using the light source, the NSC ray-tracing model, and the detector. Irradiance data can be computed for each of a plurality of pupil sizes. The method can further include evaluating ND by analyzing the respective irradiance data for each of the pupil sizes. Also described herein are methods for designing an ophthalmic lens edge that reduces the incidence of ND for a given ophthalmic lens by adjusting the edge thickness and/or the scatter.

La présente invention concerne des systèmes et des procédés d'évaluation de la dysphotopsie négative (ND). Un exemple de procédé peut comprendre la construction d'un modèle de traçage de rayon non séquentiel (NSC) d'un œil à l'aide d'une lentille ophtalmique, et la modélisation d'une source de lumière et d'un détecteur. Le détecteur peut être conçu pour imiter la rétine de l’œil. Le procédé peut également consister à calculer des données d'éclairement énergétique à l'aide de la source de lumière, du modèle de traçage de rayon NSC et du détecteur. Des données d'éclairement énergétique peuvent être calculées pour chacune d'une pluralité de tailles de pupille. Le procédé peut en outre consister à évaluer la ND par analyse des données d'éclairement énergétique correspondant à chacune des tailles de pupille. L'invention concerne également des procédés de conception d'un bord de lentille ophtalmique qui réduit l'incidence de la ND pour une lentille ophtalmique donnée par ajustement de l'épaisseur du bord et/ou de la diffusion.
